A magnet of magnetic moment M and having moment of inertia I , is suspended to orient freely in the horizontal plane under the influence of earth's magnetic field . If it is slightly disturbed , the time period is given by

A freely suspended magnet lies in the horizontal plane at ___________of earth.

One bar magnet is suspended so as to rotate freely in horizontal magnetic field. Then .....

A bar magnet of magnetic moment M and moment of inertia I is freely suspended such that the magnetic axial line is in the direction of magnetic meridian. If the magnet is displaced by a very small angle (theta), the angular acceleration is (magnetic induction of earth's horizontal field= B_(H) )

A small compass needle of magnetic moment ‘M’ and moment of inertial ‘I’ is free to oscillate in a magnetic field ‘B’. It is slightly disturbed from its equilibrium position and then released. Show that it executes simple harmonic motion. Hence, write the expression for its time period.
